Warning - Blonde joke ahead
My favourite joke (it may be from this forum)
A blonde driver is pulled over for speeding, by a blonde policewoman, and is asked for her driver's license.
The driver begins rummaging through her purse, and asks what the license looks like.
The policewoman says that it is small, rectangular, and has the driver's picture on it.
The driver finds a small mirror in her purse, looks at it, says: "Oh, this is it," and hands it to the officer.
The policewoman looks at the mirror, and says: "Oh, I didn't realize that you were a cop, too. You can go."
